llwirin France arent @terreno JOI-IN HOLMES HUNTRESS, OF JANFSVILLE, 'WISCONSIN- IMUTMLCKEl SPECIFICATION forming part of Letters Patent No. 678,737, dated July 16, 1901. Application niet my 2,1901. serai No. 58,516. (no man.)

To @ZZ whom, t may concern:

Beit known that LJ @HN HOLMES HUN'rREss, a resident of Janesville, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Nut- Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved nutlock, and more particularly to an improved` lock for nuts, bolts, burs, and the like, the object of the invention being toprovide a device of this character which will serve the double function of a washer and lock and securely hold the nut,- bolt, or bur against possibility of accidental turning, but permit its ready removal when desired.

With this object in view the invention consists in certain novel features of construction and combinations and-arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure lis a View illustrating my improvements applied to railway-rails. Fig. 2 is a view in section of the same. Figs. 3 and 4 are views of opposite sides of the lock removed, and Fig. 5 is a view of a modified form of my invention adapted for use on wooden articles.

l represents an ordinary railroad-rail; 2 2, fish-plates on opposite sides thereof 5 3, a bolt passed through the rail and fish-plates, and et a nut screwed onto the threaded end of the bolt. The nut shown in the drawings is hexagonal, but may be of other shape, and one fish-plate is provided with a downwardlycurved flange 5n to overlap the rail-iiange; but this ish-plate iiange 5UL may be dispensed with as desired.

Before screwing 4the nut on the bolt my improved washer 5 is disposed thereon. This washer or ring 5 is preferably circular in general shape to receive the bolt and is rough-A ened or serrated on its inner face to firmly engage the iish-plate. An angular bail or frame 6 is made integral with the lower portion of washer 5 and projects to the sides thereof, as shown at 7, to form a long bearing against either the flanged lower edge of the fish-plate or the flange of the rail, as the case may be, to prevent turning of the washer and bail. The bail or frame G is rectangular in general shape, forming parallel side sections S and top 9, which latter is preferably curved sharply upward between its ends, forming the notch lO to receive a corner of Vthe nut, as will now be explained.

vThe operation of my improvements is as follows: The washer and bail being perfectly flat, the nut 4; can be screwed home on bolt 3, forcing the roughened or corrugated face of the washer 5 into close engagement with the fish-plate 2. When in this position, the upper end of bail or frame 5 is bent outward until the notched upper portion IO engages the upper corner of the nut, when the side portions 8 of the bail will lie beside the sides of the nut and together with the notched upper portion of the bail prevent possibility of the nut accidentally working loose. To remove the nut, the bail 5 is forced back against the fish-plate 2 and out of the path of the nut.

When the lock is to be used on wooden articles, I preferably provide teeth ll on the i11- ner face of the washer, as shown in Fig. 5, to be forced into the wood by the nut and prevent turning of the washer.

Various other slight changes might be resorted to in the general form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I would have it understood that 'I do not wish to limit myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure byLetters Patent, is

l. A nut-lock comprising a bail and an integral washer inclosed within said bail, said washer having an inner corrugated or rough ened biting-face.

2. A nut-lock comprising a circular ring or washer having a roughened or corrugated face, an angular bail of malleable metal surrounding the washer and made integral with the washer at the lower end of the latter.

In testimony whereof I have signed this specication in the presence of two subscribing witnesses.
